Multiple sequence alignment Benchmark Data set
1. 汇总: 序列比对标准数据集: http://www.drive5.com/bench/
This is a collection of multiple alignment benchmarks in a uniform
format that is convenient for further analysis. All files are in
FASTA format, with upper-case letters used to indicate aligned
columns.
See References below for original sources of benchmark data.
Benchmarks are:
--------------------------1---------------------------
bali2dna
BALIBASE v2, reverse-translated to DNA
bali2dnaf
Bali2dbn, with frame-shifts induced by random insertions of one
or two nucleotides into the middle 50% of exactly one sequence
in each set.
bali3
BALIBASE v3.
bali3pdb
BALIS, the structural subset of BALIBASE v3.
bali3pdbm
MU-BALIS, i.e. BALIS re-aligned by MUSTANG.
---------------------------2--------------------------
ox
OXBENCH.
oxm
MU-OXBENCH, i.e. OXBENCH re-aligned by MUSTANG.
oxx
OXBENCH-X, i.e. the Extended set in OBENCH.
---------------------------3--------------------------
prefab4
PREFAB v4.
prefab4ref
PREFAB-R, i.e. the pair-wise reference pairs in PREFAB v4.
prefab4refm
MU-PREFAB-R, i.e. PREFAB-R re-aligned by MUSTANG.
---------------------------4--------------------------
sabre
Consistent multiple alignments constructed from SABMARK v1.65.
sabrem
MU-SABRE, i.e. SABRE re-aligned by MUSTANG.
-----------------------------------------------------
Directory structure under each benchmark is:
in/
Input sequences.
ref/
Reference alignments. Upper-case regions indicate conservative
regions that are intended for use in assessment. Lower-case regions
should not be used.
info/
Contains ids.txt (list of set identifiers that are filenames in ref/
and in/), nrseqs.txt (number of sequences in each set), and
pctids.txt (%id in conservative regions in each set).

This is a quality scoring program that compares two multiple sequence alignments: an alignment to be evaluated (the "test" alignment) and a second alignment that is believed to be correct (the "reference" alignment). The program outputs the following scores:
- The PREFAB Q score (aka the Balibase SPS score or the Developer score).
- The Modeler score
- The Cline et al. shift score
- The Balibase TC (total column) score
